Background

In a large-scale calculation task, errors generated by the quantum system can be accumulated continuously, and a correct calculation result cannot be given finally. Thus, a mechanism of fault-tolerant quantum computation needs to be introduced, and errors occurring in the computation are corrected in time. Quantum error correction (Quantum Error Correction, abbreviated QEC) refers generally to various schemes for resolving errors generated during a series of quantum operations on a quantum chip. One quantum error correction method is to use quantum error correction codes, i.e., by treating a plurality of physical qubits as one logical qubit, thereby finding and correcting errors without destroying the information stored in the logical qubit.

However, after encoding using the quantum error correction code, in order to obtain physical bits having errors, a plurality of physical bits need to be decoded, and a plurality of decoding information needs to be recorded during the decoding process, which results in low decoding efficiency.

FIG. 2 is a block diagram of a computing environment 201, as shown in FIG. 2, that includes a plurality of computing nodes (e.g., servers) operating on a distributed network (shown as 210-1, 210-2, …) provided by embodiments of the present invention. The computing nodes each contain local processing and memory resources and end user 202 may run applications or store data remotely in computing environment 201. An application may be provided as a plurality of services 220-1,220-2,220-3 and 220-4 in computing environment 201, representing services "A", "D", "E", and "H", respectively.

In the above-described operating environment, in response to the above-described problems mentioned in the present application, the present application provides an error symptom information processing method one as shown in fig. 3. Fig. 3 is a flowchart of a first error symptom information processing method according to embodiment 1 of the present invention, and as shown in fig. 3, the flowchart includes the steps of:

step S302, error symptom information obtained after the quantum circuit is measured is obtained;

as an alternative embodiment, the execution subject of the method of this embodiment may be a terminal or a server for processing error symptom information. The types of the terminals may be various, for example, a mobile terminal with a certain computing capability, a fixed computer device with a computing capability, or the like. The types of the servers may be various, for example, a local server or a virtual cloud server. The server may be a single computer device according to its computing power, or may be a computer cluster in which a plurality of computer devices are integrated.

As an alternative embodiment, the quantum circuit may refer to a set of devices for implementing a certain function, for example, may be a quantum chip. The device set includes a variety of devices, such as, for example, qubits, quantum gates, quantum controllers, quantum readout resonators, and the like. The quantum circuit may also be, for example, a quantum processor for performing quantum computing processing.

As an alternative embodiment, when performing error correction on a quantum circuit, for example, when performing quantum error correction using a quantum error correction code, a plurality of physical bits are regarded as one logical bit, and a signal that can be detected after an error occurs in a physical bit is used to perform corresponding correction on the error detected in the physical bit. The error symptom information obtained after the measurement of the quantum circuit is symptom information obtained after the measurement of a plurality of physical bits in the quantum circuit. In general, after a physical bit is in error, a corresponding error symptom signal may be detected at a detection point related to the physical bit, so as to obtain error symptom information at the corresponding detection point. Therefore, in the subsequent determination of the error-occurred bit, the detected error symptom point needs to be matched, so that the error-occurred bit is determined based on the matched error symptom point pair, and further, the error correction processing is performed in a targeted manner.

As an optional embodiment, the error symptom information processing method according to the embodiment of the present invention may be a simulation processing method, that is, decoding error symptom points in a quantum circuit by adopting an error symptom map in a computer simulation manner, implementing error symptom information processing based on a set expansion and a set boundary feature information recording manner, and further decoding a quantum device in which an error occurs in the quantum circuit.

Step S304, generating an error symptom map comprising a plurality of error symptom points based on the error symptom information;

as an alternative embodiment, when generating an error symptom map including a plurality of error symptom points based on error symptom information, the following processing manner may be adopted: firstly, generating a plurality of corresponding error symptom points based on a plurality of pieces of information included in the error symptom information; determining edges for characterizing quantum devices in the quantum circuit; an error symptom map is generated by connecting one or more edges between any two of the plurality of error symptom points.

When the plurality of error symptom points are generated based on the plurality of pieces of information included in the error symptom information, the corresponding error symptom information may be obtained at the corresponding detection points after measuring the bits in the quantum circuit. When the corresponding plurality of error symptom points are generated, information describing each error symptom point is included, for example, the number information of the plurality of error symptom points, the relative position information among the plurality of error symptom points, and the like.

As an alternative embodiment, on the error symptom map, one or more edges are connected between any two error symptom points in the plurality of error symptom points, and edges in the one or more edges may represent qubits in the quantum circuit.

As an alternative embodiment, the type of qubit may be various, for example, a Transmon qubit, or a Fluxonium qubit.

As an alternative embodiment, when generating an error symptom map including a plurality of error symptom points based on the error symptom information, the generated error symptom map may include the plurality of error symptom points, and any two error symptom points among the plurality of error symptom points are connected by one or more edges, and the length of the edge may be regarded as a unit length in the error symptom map, that is, each error symptom point is connected by the unit length. Therefore, the generated error symptom map includes a plurality of edges and connection points where the edges are connected, and error symptom points may exist on the nodes where the edges are connected, and the error symptom points are discretely distributed on the nodes formed by the plurality of points. It should be noted that, more intuitively, a square may be built based on a standard unit length, that is, the edge for connecting between a plurality of error symptom points, where the error symptom points are scattered on the vertices of the square, that is, the error symptom map is a square.

Step S306, expanding the error symptom map by using a plurality of error symptom points as initial sets respectively, and recording boundary characteristic information of the expanded sets;

as an alternative embodiment, when expanding on the error symptom map with a plurality of error symptom points as initial sets respectively and recording boundary feature information of the expanded sets, the expanding of the sets can be performed based on one expanding step, for example, the expanding step can be determined first, for example, half of the edges are determined as expanding step, that is, the expanding is performed based on half edges; then, on the error symptom map, a plurality of error symptom points are respectively used as initial sets, and expansion is carried out based on expansion step length; after performing the multiple expansions, recording boundary feature information of the expanded set includes: half or full. The expansion step length is expanded by a half side, so that the granularity of the set merging is smaller compared with the whole side expansion, the expansion precision can be effectively controlled, and the set merging is finer. In the case of expansion based on half, since the unit of distance connection between each error symptom point is a side, the boundary of the set obtained after expansion may be half or full after one or more expansion of the set. After the expansion is carried out for odd number times, the obtained set after the expansion is half, and after the expansion is carried out for even number times, the obtained set after the expansion is full.

As an optional embodiment, when the multiple error symptom points are respectively used as the initial sets to be expanded, the multiple initial sets can be expanded at the same time, and then merging operations of the sets are uniformly judged; the method can also be used for executing one-time expansion on a plurality of error symptom points according to a certain sequence, and processing the merging operation of the current set and other sets after expansion. After the set is expanded once, the boundary feature information of the set is recorded, and it should be noted that the boundary feature information is used for describing whether the expansion of the set is half-expansion or full-expansion, that is, whether the expanded boundary is half-expansion or full-expansion. Compared with the prior art, when the set is expanded, the information of each side after expansion needs to be maintained, for example, when one set comprises a plurality of sides, the corresponding information of each side needs to be maintained, so that the quantity of information in the set expansion process is effectively saved, the data processing operation is effectively reduced, and the set merging efficiency is improved.

When the above-mentioned multiple error symptom points are combined, that is, when the sets are combined, the sets are combined in adjacent sets, that is, the set closest to the current set, regardless of whether the multiple sets are simultaneously expanded or the sets are expanded in a certain order.

Step S308, based on the boundary feature information of the expanded set, performing set merging processing until the number of error symptom points included in the set obtained after set merging is even, and ending the expansion merging operation to obtain one or more target sets for a plurality of error symptom points.

As an alternative embodiment, when performing the set merging process based on the boundary feature information of the expanded set, a process involving determining the merging condition of the set may be implemented, for example, based on the following processes: detecting whether the types of the boundary characteristic information of two adjacent sets are the same or not based on the boundary characteristic information of the expanded sets; detecting whether the two adjacent sets accord with the merging condition or not when the detection result is that the boundary characteristic information types of the two adjacent sets are the same; and under the condition that the detection result is that the two adjacent sets meet the merging condition, executing set merging processing on the two adjacent sets. The boundary feature information of the two adjacent sets is the same type, and may be considered as a precondition for merging the sets, and based on this condition, it may be confirmed that the sets are merged in the same batch of expansion. When the set is expanded, the expansion is performed according to a half expansion mode, namely, only half expansion is performed each time, so that boundary characteristic information of the set corresponding to the expansion of the same batch is the same, namely, half expansion or full expansion is performed. Based on this condition, non-uniformity of set merging is effectively avoided. The boundary feature information types are the same and include: the boundary characteristic information of two adjacent sets is half or the boundary characteristic information of two adjacent sets is full.

The two adjacent sets may be adjacent to each other with only one side or with a plurality of sides. The above-mentioned merging condition may refer to whether two adjacent sets can be connected together after expansion, that is, whether the expanded half sides or the whole sides can be connected together, if so, the merging condition may be considered to be satisfied, and if not, the merging condition may not be considered to be satisfied, and the expansion needs to be continued.

As an alternative embodiment, after performing the expansion a plurality of times, recording the boundary feature information of the expanded set includes: half or full edge comprising: the boundary feature information of the extended set corresponding to the record update is also different because of the difference between the single-side extension and the full-side extension. For example, in the case that the current extension is a half extension of the generation half, recording boundary feature information of the extended set as a newly increased half, wherein the newly increased half contains a boundary of a previous extension of the current extension; and recording boundary characteristic information of the set after expansion as half-completion under the condition that the current expansion is full-side expansion of the half-completion, wherein the half-completion does not contain the boundary of the previous expansion of the current expansion.

Therefore, the boundary feature information after the set expansion is recorded is the information corresponding to the next expansion after the set expansion. For example, after half expansion, the next expansion is a full half, so in the case of the current expansion being a half expansion that produces half, the boundary feature information of the set after expansion is recorded as a new half, where the new half contains the boundary of the previous expansion of the current expansion. After the full-side expansion, the next expansion is a new half-side expansion, so that when the current expansion is the full-side expansion of the full-side expansion, the boundary characteristic information of the set after the expansion is recorded as the half-side expansion, wherein the half-side expansion does not contain the boundary of the previous expansion of the current expansion.

In addition, the half-extension or full-extension described herein is related to the first extension, and since the first extension is the half-extension, the odd extensions related subsequently are the half-extensions, and the even extensions are the full-extensions.

As an alternative embodiment, when performing the set merging process based on the boundary feature information of the expanded set, the number of error symptom points included in the merged set based on the number includes: based on the boundary characteristic information of the expanded set, under the condition that set merging occurs, counting the number of error symptom points included after the set merging; and if the number is odd, continuing to execute the set extension merging operation, otherwise ending the set extension merging operation. After the aggregation is combined, counting the number of the error symptom points included in the combined aggregation, continuously executing the aggregation expansion and combination operation when the counted number is odd, and ending the aggregation expansion and combination operation if the counted number is even, so that the number of the error symptom points included in the combined aggregation is even finally.

As an alternative embodiment, after obtaining one or more target sets for a plurality of error symptom points, quantum error correction processing may be performed subsequently based on the obtained one or more target sets. For example, the following processing may be employed: respectively matching error symptom points included in one or more target sets in the set to obtain a matching result; determining an error quantum device in the quantum circuit based on the corresponding matching result; and performing error correction processing on the error quantum device. Based on the error symptom map, an even number of error symptom points are included in the combined set, so that the even number of error symptom points in the set can be matched in pairs, a path between the two points is determined based on the matching result, and an error quantum device in the quantum circuit, such as a quantum bit with an error, is determined based on the path.

By the above processing, when an error symptom map including a plurality of error symptom points is generated based on error symptom information of a quantum circuit in order to realize quantum error correction processing based on a quantum error correction code, the plurality of error symptom points are respectively expanded as a start set on the error symptom map, boundary feature information of the expanded set is recorded, and set merging processing is performed based on the boundary feature information of the expanded set until the number of error symptom points included in the set obtained after set merging is an even number. The information of each side of the set is recorded and maintained based on boundary characteristic information of the set after the set is used for replacing, so that the information maintenance in the set merging process is effectively reduced, the data processing of the set merging is effectively improved, and the decoding efficiency based on the quantum error correction code is improved.

In another alternative embodiment of the present invention, there is further provided a second error symptom information processing method, and fig. 4 is a flowchart of the second error symptom information processing method according to embodiment 1 of the present invention, as shown in fig. 4, where the flowchart includes the following steps:

step S402, receiving symptom information processing instructions on a display interface;

step S404, responding to the symptom information processing instruction, obtaining error symptom information obtained after the quantum circuit is measured, and displaying an error symptom map comprising a plurality of error symptom points on a display interface based on the error symptom information;

step S406, in response to the symptom map processing instruction, expanding on the error symptom map by using a plurality of error symptom points as initial sets respectively, recording boundary characteristic information of the expanded sets, and executing set merging processing based on the boundary characteristic information of the expanded sets until the number of error symptom points included in the sets obtained after the set merging is even, and ending the expansion merging operation to obtain one or more target sets for the plurality of error symptom points;

step S408, displaying one or more target sets on the display interface.

Through the processing, in order to realize quantum error correction processing based on quantum error correction codes, symptom information processing instructions are received on a display interface; responding to the symptom information processing instruction, acquiring error symptom information obtained after the quantum circuit is measured, and displaying an error symptom map comprising a plurality of error symptom points on a display interface based on the error symptom information; responding to a symptom map processing instruction, respectively expanding a plurality of error symptom points serving as initial sets on the error symptom map, recording boundary characteristic information of the expanded sets, and executing set merging processing based on the boundary characteristic information of the expanded sets until the number of error symptom points included in the sets obtained after the set merging is even, and ending the expansion merging operation to obtain one or more target sets aiming at the plurality of error symptom points; one or more target sets are displayed on a display interface. Based on the interface interaction mode, the information of each side of the set is recorded based on boundary characteristic information of the set after the set is adopted to replace the information of each side of the set, so that the information maintenance in the set merging process is effectively reduced, the data processing of the set merging is effectively improved, and the decoding efficiency based on quantum error correction codes is improved; and the whole processing based on the error symptom points in the error symptom map can be more visual by the interface display mode, so that the clarity of data processing is realized.

Based on the above embodiments and alternative embodiments, an alternative implementation is provided.

In the related art, to implement quantum error correction, a potential fault-tolerant mechanism is to encode logic bits using quantum surface codes and perform error correction using the Union-Find decoder (i.e., UF decoder) algorithm during computation. UF decoder is an algorithm that performs error correction on quantum surface codes. After the logic qubit is encoded into the physical qubit through the error correction code, if the physical qubit is in error, an error symptom signal (syndrome) can be detected, and the decoding process is to reversely infer the error through the obtained error symptom signal, and a corresponding correction scheme is provided. For surface codes, decoding may be achieved by matching error symptom signals (represented in the figure in dots, and thus may also be referred to as error symptom points) on the graph. Fig. 5 is a schematic diagram of matching error symptom points on a graph when quantum error correction is performed based on a surface code according to an alternative embodiment of the present invention, as shown in fig. 5, and is characterized by a square division manner in the graph, where points on the square represent syncrone where errors may exist, and lines between the points represent bits where errors may occur. The decoding process of the UF decoder involves a series of operations on the collection of points and edges on the graph. In the related art, each point where the syncrone is detected is taken as a set at the beginning, then in each operation, the algorithm expands the set containing an odd number of syncrones outwards by half, and maintains the set when merging occurs, using the Union-Find data structure until all sets contain an even number of syncrones. And finally, performing syndrome matching in each set to obtain a final decoding result.

If the UF decoder is directly realized according to the definition, the set needs to be maintained by taking a half edge as a unit, the code realization is more complex, and the decoding efficiency is lower. In view of this, in alternative embodiments of the invention, an equivalent but simpler implementation is provided.

Note that the boundaries of each set are either all half-edges or all full-edges, dividing the expansion of the set into two cases, a "half-edge expansion" that produces half-edges and a "full-edge expansion" that complements half-edges, respectively. In expanding the current set, if it is merged with other sets, it is noted that only the merging can occur with the set on which the same type expansion was last performed. It should also be noted that when maintaining the boundaries of the collection, the new boundaries do not contain the boundaries before this expansion when full-edge expansion is performed, because these edges are already completely contained inside the collection after expansion, and the new boundaries should contain the boundaries before expansion when half-edge expansion is performed.

Through the processing, the boundary state of each set can be directly recorded by adopting the mode of defining half extension and full extension, and the independent maintenance of each side state is omitted, thereby simplifying the realization of the algorithm.

It should be noted that, the user information (including but not limited to user equipment information, user personal information, etc.) and the data (including but not limited to data for analysis, stored data, presented data, etc.) related to the present application are information and data authorized by the user or fully authorized by each party, and the collection, use and processing of the related data need to comply with the related laws and regulations and standards of the related country and region, and provide corresponding operation entries for the user to select authorization or rejection.
